The story takes place in a coastal defense position in Taiwan in the 1970s. Goudan (played by Hao Shaowen) is a naughty child in the village. He follows the duty officer Wu Banzhang (played by Wu Zongxian) all day long to do sneaky things and live a carefree life. Due to the lax military discipline and the really outrageous performance, the boss transferred a new captain (played by Wu Qilong), who vowed to transform this group of rabble in three months. After a period of ridiculous rectification, military discipline has indeed improved significantly, and it has performed outstandingly in the Sino-US military exercises. Although it lost to the US military by a narrow score, the Navy Command highly praised the new captain's experience in leading troops, and even Goudan's class owner (played by Weng Hong) also had a good impression of him. The new captain declined the promotion of his superiors and persuaded his father, who was a general, to stay here. His father finally agreed to his request.
